ASTM A213 Grade T5 Alloy Steel Seamless Tube Heat Exchanger Tube

What is ASTM A213 material?

ASTM A213 is a specification that covers seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. These tubes are designed for use in high-temperature and corrosive environments, making them suitable for applications in power plants and petrochemical industries. The material is available in various grades, such as ferritic grades T5, T9, and T11, and austenitic grades including TP304.

 

​​ASTM A213 T5 seamless alloy tubes belong to the ferritic steel category under the ASTM A213 standard. They exhibit excellent heat resistance and corrosion resistance in hot petroleum media. ASTM A213 T5 alloy tubes contain multiple alloying elements including silicon, molybdenum, nickel, chromium, manganese, and vanadium. These elements contribute to enhanced wear resistance, toughness, and strength. The high thermal strength of A213 T5 cold-rolled alloy tubes makes them suitable for pressure equipment operating at temperatures up to 1000°C.​

 

What size is ASTM A213 tubing?

ASTM A213 Stainless Steel Tube in this grade is generally specified in sizes of 3.2mm, having an internal diameter of 127mm, with an outside diameter in the range of 0.4mm up to 12.7mm. They are generally divided into T5, T9, T11, T12, T22, and T91 types.
